The fire-safe high-performance butterfly valve is designed with two distinct seats to ensure optimal functionality and safety. The primary seat material, RPTFE (Reinforced Poly Tetrafluoroethylene), provides excellent sealing properties, achieving a tight shut-off and effectively preventing leakage. This soft seat material enhances the overall performance of the valve. In addition, the valve is equipped with a secondary fire-safe seat made of metal, which offers superior resistance to high temperatures and is capable of withstanding the harsh conditions of a fire. The combination of the RPTFE soft seat and the metal fire-safe seat ensures reliable performance under both normal and emergency conditions, making this valve an ideal choice for applications where safety and efficiency are critical.
